Plan Something Awesome

How It Works

1

Tell Your Assistant

Email pm@planwell.co with your event details: date, budget, guest count, and preferences.

2

Research & Iterate

Your assistant researches vendors, checks reviews, and sends options. Iterate together over email to explore possibilities.

3

Decide with Math

Constraint programming finds the provably optimal vendor combination within your budget and timeline. Not suggestions—guaranteed best solutions.

4

Make It Happen

Your assistant coordinates vendors, sends booking confirmations, and proactively reminds you of deadlines. You stay in the loop over email.

Behind the scenes: Our constraint programming solver evaluated 243 possible vendor combinations in 0.4 seconds to find this optimal solution.

Why Planwell is Different

Regular AI chatbots only give suggestions. Planwell is a complete planning system with research, optimization, coordination, and execution tools built in.

❌ Regular AI Assistants

  • Struggle with calculations
    Hallucinate numbers and can't solve complex budget constraints
  • Can't reach out to vendors
    Only research and suggest—you handle all coordination
  • No specialized planning tools
    General-purpose chatbots without event-specific workflows
  • "Good enough" recommendations
    Suggest options sequentially, can't guarantee optimal solution

✅ Planwell (AI + Math)

  • Mathematically guaranteed optimal
    Constraint programming solver handles complex calculations correctly
  • Reaches out to vendors for you
    Emails vendors for quotes, tracks responses, follows up
  • Purpose-built planning tools
    Timeline scheduling, dependency tracking, budget optimization
  • Provably best solution
    Evaluates ALL vendor combinations to find optimal plan

How it works:

Planwell uses constraint programming (CP-SAT solver) to explore thousands of vendor combinations in seconds and guarantee the optimal solution. The same math used by airlines to schedule flights and manufacturers to plan production.
